Additional Guardrail to block creation of account-level AWS IAM Identity Center instances
A new Guardrail has been added under the AWS IAM Identity Center header titled Block creation of account-level instances for IAM Identity Center.
This Guardrail will prevent member AWS accounts for creating any account-level instances of IAM Identity Center, ensuring that only a centrally managed IAM Identity Centre exists within the AWS management account.
To enable this visit the configurable service page Configurable Guardrails.
